5.3 Tryptophan metabolites Tryptophan metabolites are generated either through direct decomposition of tryptophan by gut microbiota (e.g., Clostridium, Escherichia coli ) into indole derivatives (such as IPA and indole-3-acetic acid (IAA)) or via host-cell-mediated processes (e.g., indoleamine 2,3-dioxygenase 1(IDO1)-catalyzed kynurenine production, 5-hydroxytryptamine (5-HT) synthesis by enterochromaffin cells) in coordination with microbial metabolism
Liquid-Phase Peptide Synthesis (LPPS): Used for longer or more specialized peptide sequences, LPPS can sometimes offer cost advantages for complex structures
